Answer
Using the information in Figure Q4, comment on the most suitable wind turbine for
installation in a farm where the average wind speed over the year is 12m/s.
We need more data to decide
The 3-bladed because it is the most common
The 2-bladed because of the high Cp
The 1-blade because it has high enough CP over a range of wind speeds
